It's basically gone through three phases: # The dawn of time to maybe 40 years ago: it's a solid. # About 40 years ago: it's a liquid, hur hur hur. # As sanity prevailed after a few years of that nonsense: it's an amorphous solid.

Why the burette is clamped vertically?
A burette can be a hollow glass (or plastic) tube open at the top, with a small tap at the bottom. There may also be a scale etched down the tube. The burette allows a certain amount of liquid past the tap. So, obviously, unless clamped vertically, the liquid would simply pour out of the glass tube.
Is there more atoms in a glass of water than there is people in the world?
A small 100 ml glass of water has something like 10^25 atoms in it. That number is greater than the number of people who have ever existed on the planet, past and present. In fact there are more atoms in a glass of water than there are grains of sand on the earth.
A glass blower can bend and shape a piece of glass that has been amorphous solid?
Its an amorphous solid. When the glassblower blows into the glass, it expands just like a balloon. Crystalline solids can't expand like that because their atoms are held together in a rigid lattice. But amorphous solids have many of the proprties of liquids and can flow past each other, allowing the glass to stretch like the skin of a balloon.
Does a solid liquid or gas have particles that vibrate but cannot move past each other?
solid
Scientific definition of pure liquid?
liquids have particles but the bonds are not very strong so the paticles can move past each other
Is glass a fluid?
Past its melting point yes, this is just the same as asking if ice is a liquid.
How do particles in a liquid make it possible to pour liquid into a glass?
Particles in a liquid move past each other, allowing the liquid to flow smoothly. When you tilt a container to pour a liquid, the particles are able to rearrange and flow into the glass due to their ability to move and adapt to the new shape. This allows the liquid to flow and fill the glass evenly.
